“SVT keeps the Shelby GT500 on the cutting edge of technology and takes muscle car performance to new heights,” said Jost Capito, Ford’s director of Global Performance Vehicles. “We encapsulated every aspect of performance in this car – whether it’s 0-60, top speed, racetrack or quarter-mile times. Beyond that, the daily driver will also find the car fits their needs.”
Power comes from a 5.8-liter V8 with aluminum-block engine. It produces 650hp and 600 lb-ft, yet the 3850 lb car is exempt from the gas-guzzler tax.
To achieve this power, everything has been optimized, including a new supercharger, cross-drilled block and heads, updated camshafts, a carbon fiber driveshaft plus upgraded clutch, transmission and axles.
The larger supercharger is a TVS series 2300, which creates 2.3 liters of displacement and is a unique design to the 5.8L engine.
The entire cooling system has been updated to include a more efficient charge-air cooler with a new intercooler pump and heat exchanger. The cooling fan is also larger and the fan shroud has high-speed pressure-relief flaps.
The six-speed manual transmission has upgraded gears with different ratios, as well as new bearings and housing to manage the torque. The final-drive ratio is now 3.31:1 for optimized overall gearing to complement the massive torque. The clutch has increased torque and rpm capacity and uses a dual-disc design.
When customers order the optional Performance Package, they get a Torsen limited-slip differential to improve traction under track conditions. A new launch control system was also developed that lets drivers set the desired launch RPM depending on tire temperature, road surface or other conditions. Uniquely, the SVT launch control is integrated into both the engine control and traction control systems.
The Shelby GT500 also get a new Brembo brake system with six-piston front calipers and larger rotors all round to reduce brake fade. New pads achieve higher deceleration.
With its infeasibly high top speed, significant aerodynamic work was done to ensure the car has downforce at high speed. Therefore, the front spoiler and splitters were modified, resulting in 33% more effective aero loading at 160mph compared to the 2011 model.
The AdvanceTrac settings and steering assist levels have all been re-tuned to account for the updated content. Yet both systems can be disabled for track use, or fully engaged for maximum safety in normal driving or in bad weather. An intermediate sport mode allows drivers to push their cars hard at the track without completely disabling the safety systems, permitting more aggressive driving before the traction control and electronic stability control intervene.
“Drivers can choose their settings instead of a computer making the selection,” said Jamal Hameedi from SVT. “Nearly every system can be tailored to the situation, including the Bilstein electronic adjustable suspension, launch control, AdvanceTrac and steering assist levels.”
The 2013 Shelby GT500 will offer two new sets of forged aluminum wheels, including a unique wheel for cars with the optional packages. The 19-inch front and 20-inch rear wheels are coupled with Goodyear Eagle®F1 SuperCar G: 2 tires on all configurations.
The two new optional 2013 packages include the Performance Package with SVT-designed Bilstein electronic adjustable dampers accessed on the dash with a simple push of a button. Normal mode gives customers a more comfortable ride over road irregularities. Sport mode is all about performance, delivering improved response time on the track, less body roll while cornering and pitch under braking. The Torsen limited-slip differential also comes with the Performance Package.
Enthusiasts can upgrade their Performance Package with an additional Track Package for all-out performance. It comes with an external oil cooler, differential cooler and transmission cooler for further durability.
The 2013 Ford Shelby GT500 will be built at the AutoAlliance International Plant in Flat Rock, MI.
